Slits for Monochromators and Spectrographs

Overview

To operate any monochromator or spectrograph, slits are required at all entrance and exit ports. The slits offered for use with Oriel^® monochromators and spectrographs all have 1.5-inch male flanges, allowing them to be easily connected to the wide variety of Oriel accessories and instruments. The resolution of the monochromator is related to the grating dispersion and the slit width, and is calculated to be the reciprocal dispersion multiplied by the slit width.

Fixed slits for high accuracy and repeatability

Fixed slits are a low cost alternative with excellent repeatability and are a good choice when only a few slit sizes are required. Avaialble in widths from 10 µm to 6.3 mm, they slide into the holders at all instrument ports, with the exception of those ports configured to mount a camera. The slit holders are installed by Newport during calibration of the instrument. The width and height cannot be adjusted but may be individually replaced with other slit sizes. These fixed slits are sold separately to allow customized choices based on the needs of the application. When ordering, be sure to purchase fixed slits of the same model (i.e. same size) for the input port and output port(s). Each of the fixed slits is mounted in a precision machined slide which is inserted into the 77294 or 77721 fixed slit holder. Contact us for more information.

Micrometer adjustable slits for flexibility and high throughput

A micrometer adjustable slit assembly provides versatility and convenience in changing resolution and throughput. They are ideal when the utmost accuracy and repeatability is required, especially at high resolution. These adjustable slits are continuously variable from fully closed to 3 mm width, with a narrowest practically achievable width of 4 µm. (Note that optimum spectral resolution for any monochromator is obtained with short, narrow slits.) A height adjustment slide allows variation in the height from 2 to 12 mm.

Motorized slits for remote and automated applications

Exclusive to the CS260B monochromators, the 74115B motorized slits

may be adjusted from 6 µm to 3 mm width in 6 µm steps. The slit width is controlled through the utility software, optional hand controller, optional TracQ Basic software or by using low level commands. An advantage of using motorized slits is that in addition to setting the individual slit widths remotely, the software can be configured to an automatic bandpass setting. The software adjusts the slit widths to maintain the chosen bandpass as scans are performed using multiple gratings and either output port. Motorized slits are only available on special order configuration Cornerstone 260B monochromators. Contact your Newport sales representative for more information.
